BOM publishes Central Coast waters from Cape Otway to Wilsons Promontory, but blocks application access; no forecast is scraped or presented as break-level surf.
The nearer current VIC Waves buoys are inside Port Phillip Bay, while the open-Bass-Strait Inverloch buoy is about 83 km away across Phillip Island; no observation is assigned to Gunnamatta.
No tide prediction with verified station identity, distance, datum, timezone, and current response is connected; third-party nearby-tide references are not treated as station contracts.
